Hello Roberto,
AVG Antivirus free will just protect and scan your computer. It won't delete any files from your PC. If it detects any virus in the files, it will move those files to the AVG Quarantine.
Please check if the files has been moved to quarantine- AVG > Menu > Quarantine and also in the computer recycle bin.
I can't find report in my windows 7 installation C:\ProgramData\AVG\Antivirus\report
